Calibrachoa plant named ‘Wescacream’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Wescacream’, characterized by its cascading and uniform growth habit; freely branching habit and short internodes; dense and bushy plant form; relatively small leaves; medium-sized flowers; and numerous creamy white-colored flowers.

Botanical designation: Calibrachoa sp.

Variety denomination: ‘Wescacream’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Wescacream’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The new Calibrachoa originated from a cross-pollination made by the Inventor of a proprietary selection of Calibrachoa identified as code number 01P247, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa identified as code number 01P200, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor in 2002 in a controlled environment in Südlohn, Germany as a single plant within the resulting progeny from the cross-pollination.

Asexual reproduction of the new cultivar by terminal cuttings at Südlohn, Germany since 2002, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Wescacream have not been observed under all possible environmental conditions. The phenotype may vary with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wescacream’. These characteristics in combination distinguish ‘Wescacream’ as a new and distinct cultivar:

-   -   1. Cascading and uniform growth habit.     -   2. Freely branching habit and short internodes, dense and bushy         appearance.     -   3. Relatively small leaves.     -   4. Medium-sized flowers.     -   5. Numerous creamy white-colored flowers.

Plants of the cultivar Wescacream can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa had lighter green-colored         leaves than plants of the female parent selection.     -   2. Plants of the new Calibrachoa and the female parent selection         differed in flower color as plants of the female parent         selection had yellow-colored flowers.

Plants of the cultivar Wescacream can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa had shorter internodes than         plants of the male parent selection.     -   2. Plants of the new Calibrachoa had lighter green-colored         leaves than plants of the male parent selection.     -   3. Plants of the new Calibrachoa and the male parent selection         differed in flower color as plants of the female parent         selection had purer white-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Carillon White, not patented. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the cultivar Carillon White in the following characteristics:

-   -   1. Plants of the new Calibrachoa had longer internodes than         plants of the cultivar Carillon White.     -   2. Plants of the new Calibrachoa had lighter green-colored         leaves than plants of the cultivar Carillon White.     -   3. Plants of the new Calibrachoa and the cultivar Carillon White         differed in flower color.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and for the following description were grown under conditions which closely approximate commercial production conditions during the spring and summer in a glass-covered greenhouse in Südlohn, Germany. Plants were about 20 weeks from planting rooted cuttings and grown in containers. During the production of the plants, the day temperatures ranged from 20 to 25° C., night temperatures ranged from 16 to 18° C. and light levels ranged from 3,000 to 50,000 lux.
